The Cannes Film Festival kicked off with a stylish bang for a second day in a row. Charlize Theron wore a black fringed Valentino dress that took her out of her classical look and into something more edgy. She definitely knew how to pull of the look in her blonde tresses. The blonde bombshell definitely stole the show and her legs looked endless in her little black dress! But it was this accessory that Charlize was sporting on her ring finger that caught our eye. Is that a wedding band?
